    If you topped up that lead acid battery and charged it, it might come back to life, unless the plates are melted or sulfated too badly.

    Still, it's 2019 and no one should have to mess around filling batteries.

    Yeah. Topped it up twice since I've owned that battery, so it hasn't been too bad in that department, considering.
    The cca was a bit low on the old battery though, adding another 100 seems to helps it alot when starting.

    So have you checked the voltages going into the new battery at idle and at about 4000 rpms?
    Those lithium batterys are so expensive to replace if theres any charging issues

    Yeah, it's around 13.4 at 3000, around 13.7-13.8 at 4000. It caps around there.

    Yep, that extra juice will give you a fat spark when you need it most and probably more cranking speed.

    Has anyone tried fitting a 3ln sump(with the screw-on filter) onto a 2kr/3hx motor? is the bolt pattern the same? i-img1200x900-1565260679szudch328.jpg

    The 2KR / 3HX and the 3LN1 uses the same part number for the sump's,
    the 3LN3 sump with the screw on oil filter fit's the 3LN1 so i would say yes it'll work, just make sure you use the 3LN3 / FZX250 Sump gasket too

    received_549997032247093.jpeg Picked this old girl today for very cheap, been sitting around for about 3 years, changed the oil, started it after about 6 cranks with old fuel. :dance2:

    I'm thinkin I needs a set of float needles, with the fuel pump coneccted its dumping alot of fuel into cyl 3 & 4 from the top of the carb throat, and the overflow tube on that side.

    Still gotta pull off the cam coversand check clearances, there's a little pressure coming from 2&3 when I snap off the throttle. It runs up to 14k rpm before it drops off which ain't too bad, pretty sure it's just a needle issue, flooding two cylinders while tryin to keep run etc.

    Do I keep the yellow, or paint it, if so, what colour lol

    So I went over all the fairings, plastic welded cracks up with the ol' soldering iron, used body filler to smooth it out.

    I was gonna keep it yellow, I couldn't match it very well. Decided to go the same sorta style as my other FZR but gold instead of grey.

    Im gonna take a wild guess and say that the reason I'm running on 3 cylinders might have something to do with the 0.03 intake valve clearance on cylinder 4 :confused:

    Where do you guys buy shims from? any links will be appreciated :D

    Precision shims in Melbourne. I'd recommend buying 16 new shims and keeping the old ones, voila, you now have spare shims.

    Check the float needles aren't just stuck, it happens. I rebuilt a set of ZX9R carbs yesterday with brand new needles and seats, #4 stuck and flooded for no reason. Pulled the bowl off, inspected, refit bowl, all good.
